Carbon dioxide exists naturally in the atmosphere as a result of the earth's carbon cycle. It is also there as a result of man's activities in burning fossil fuels (coal, oil and natural gas), which releases long-stored carbon dioxide to add to the greenhouse gases already there.

Methane occurs naturally in the atmosphere, but is also produced by man's cattle ranching.

Nitrous Oxide (310 times more powerful than CO2) is emitted from industry, rocket and vehicle engines and even aerosols.

CFCs (chlorofluorocarbons) are completely made by man. They were released for a while from aerosols and are now being phased out as a refrigerant.
